IMPROVEMENT lN BOOT AND SHOE SHANKS.

Specification forming part of Letters Patent No. 132,719, dated November 5, 1872.

- others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing and to the letters of reference marked thereon which form a part of this speeilication.

The nature of our invention consists in the construction and arrangement of a shank for boots and shoes, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which our invention appcrtains to make and use the same, we will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a bottom view, and Fig. 2 is a side view, of our invention.

Our shank consists of three pieces-a piece of leather, A, called the preserver, and two springs, B and O. The spring O is a light narrow spring, riveted at its ends to the spring B. The spring B is made heavier and of the form shown in Fig. 1. It is fastened on the under side of the preserver A by means of clamps e a, one at each end. At the heel ofthe spring B should be a notch or hol'eb, as a tack-guide, that the shank may be placed in its position. It is placed between the insole and sole ofthe boot or shoe where the filling is now usually inserted.

With this shank there is no filling needed,

thus saving time in the manufacture of the boot or shoe; and it also gives greater ease to the wearer, keeping the boot or shoe always up in the hollow of the foot and forming a spring-support for the same.

Having vthus fully described our invention,-

September, 1872. THOMAS H. GORDON.
